I came across one of these kits locally a couple weeks ago and am impressed. This one I don't know if it was a kit or not, but I am thinking not a kit since all the wood work looks like yours prior to fitting nose cap, butt plate, etc.. I had to use HVAC foil tape to bed the lock and tang for optimum fit & clearances which has worked pretty good for me in the past. I am going to shoot this one before I do anything further. The 50 barrel almost appears unshot and is kind of browned look similar to a BC plum brown finish, but I think it is really just patina from sitting in a closet - the grooves in barrel and inside of drum below nipple are still shiny which makes me think unshot - the 54 barrel has been shot but not much and someone did a good job of barrel cleaning, but it amazes me why no one ever cleanes around nipple - just a little minor pitting there that would disappear if I browned with Laurel Mtn Forge. If you got any other pics of your progress I would be interested in them so I can learn. THANKS
